ER:ONE 105 Di2

ER:ONE - Aero/Racing

The ER:ONE road frame represents a step forward in structural engineering. To achieve the combined goals of low weight, high stiffness, and reduced aerodynamic drag, every stage of development demanded precision. Each carbon ply is strategically oriented, resin ratios are optimized for strength-to-weight efficiency, and tube profiles are refined through repeated simulation and testing. From layup design to functional stress analysis, every parameter is verified and re-evaluated, ensuring a frame that balances efficiency, durability, and speed under real-world racing conditions.
